The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:2261 advisory.

    Red Hat Ceph Storage is a scalable, open, software-defined storage platform     that combines the most stable version of the Ceph storage system with a     Ceph management platform, deployment utilities, and support services.

    Security Fix(es):

    * ceph: cephx protocol is vulnerable to replay attack (CVE-2018-1128)

    * ceph: cephx uses weak signatures (CVE-2018-1129)

    * ceph: ceph-mon does not perform authorization on OSD pool ops (CVE-2018-10861)

    For more details about the security issue(s), including the impact, a CVSS     score and other related information refer to the CVE page(s) listed in the Reference section.

    Enhancement(s):

    * Ceph OSDs now logs when they shutdown due to disk operations timing out by default. (BZ#1568897)

    * The `radosgw-admin orphans find` command can inadvertently remove data objects still in use, if followed     by another operation, such as, a `rados rm` command. Users are now warned before attempting to produce     lists of potentially orphaned objects. (BZ#1573656)

    * The 'ceph-osdomap-tool' now has a 'compact' command to perform offline compaction on an OSD's 'omap'     directory. (BZ#1574231)

    * For S3 and Swift protocols, an option to list buckets/containers in natural (partial) order has been     added. Listing containers in sorted order is canonical in both protocols, but is costly, and not required     by some client applications. The performance and workload cost of S3 and Swift bucket/container listings     is reduced for sharded buckets/containers when the `allow_unordered` extension is used. (BZ#1595374)

    * An asynchronous mechanism for executing the Ceph Object Gateway garbage collection using the `librados`     APIs has been introduced. The original garbage collection mechanism serialized all processing, and lagged     behind applications in specific workloads. Garbage collection performance has been significantly improved,     and can be tuned to specific site requirements. (BZ#1595383)

    Bug Fix(es):

    These updated ceph packages include numerous bug fixes. Space precludes     documenting all of these changes in this advisory. Users are directed to the Red Hat Ceph Storage 2.5     Release Notes for information on the most significant bug fixes for this release:

The SUSE Linux Enterprise 15 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2018-14617: Prevent NULL pointer dereference and panic in hfsplus_lookup() when opening a file (that is purportedly a hard link) in an hfs+ filesystem that has malformed catalog data, and is mounted read-only without a metadata directory (bsc#1102870)

CVE-2018-14613: Prevent invalid pointer dereference in io_ctl_map_page() when mounting and operating a crafted btrfs image, caused by a lack of block group item validation in check_leaf_item (bsc#1102896).

CVE-2018-10940: The cdrom_ioctl_media_changed function allowed local attackers to use a incorrect bounds check in the CDROM driver CDROM_MEDIA_CHANGED ioctl to read out kernel memory (bsc#1092903)

CVE-2018-13093: Prevent NULL pointer dereference and panic in lookup_slow() on a NULL inode->i_ops pointer when doing pathwalks on a corrupted xfs image. This occured because of a lack of proper validation that cached inodes are free during allocation (bnc#1100001)

CVE-2018-13094: Prevent OOPS that may have occured for a corrupted xfs image after xfs_da_shrink_inode() is called with a NULL bp (bnc#1100000)

CVE-2018-13095: Prevent denial of service (memory corruption and BUG) that could have occurred for a corrupted xfs image upon encountering an inode that is in extent format, but has more extents than fit in the inode fork (bnc#1099999)

CVE-2018-12896: Prevent integer overflow in the POSIX timer code that was caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically made the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. This allowed a local user to cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls (bnc#1099922)

CVE-2018-16658: Prevent information leak in cdrom_ioctl_drive_status that could have been used by local attackers to read kernel memory (bnc#1107689)

CVE-2018-6555: The irda_setsockopt function allowed local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket (bnc#1106511)

CVE-2018-6554: Prevent memory leak in the irda_bind function that allowed local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket (bnc#1106509)

CVE-2018-1129: A flaw was found in the way signature calculation was handled by cephx authentication protocol. An attacker having access to ceph cluster network who is able to alter the message payload was able to bypass signature checks done by cephx protocol (bnc#1096748)

CVE-2018-1128: It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on network can use this vulnerability to authenticate with ceph service and perform actions allowed by ceph service (bnc#1096748)

CVE-2018-10938: A crafted network packet sent remotely by an attacker forced the kernel to enter an infinite loop in the cipso_v4_optptr() function leading to a denial-of-service (bnc#1106016)

The update package also includes non-security fixes. See advisory for details.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-001636 advisory.

    It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable     to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on     network can use this vulnerability to authenticate with ceph service and perform actions allowed by ceph     service. Ceph branches master, mimic, luminous and jewel are believed to be vulnerable.
